Keywords: Other Preclinical, Reproductive, Early Embryos
Motivation: Traditional methods for early embryos assessment are often invasive or lack detail, underscoring the necessity for non-invasive, high-resolution techniques.
Goal(s): The primary goal was to test MRS as a predictive tool for embryo viability. By leveraging microchip-based probes, we analyzed the metabolic profile of early-stage bovine embryos and oocytes. This aimed at predicting developmental outcomes with high precision and accuracy.
Approach: In total, we conducted multi-channel high-throughput spectroscopy to perform a minimally invasive analysis of 1 hour on 61 single 8-cell embryos and 84 single oocytes.
Results: We found strong correlation between spectra at the 8-cell stage and subsequent development to blastocyst.
Impact: This work offers new data for MRS and embryology, laying a foundation to improve fertility treatments by selecting viable embryos. By revealing previously inaccessible data it opens to new embryonic research, potentially revolutionizing our understanding of early developmental biology.
